Options

  1. A5.2
  2. B5.0
  3. C4.54.5
  4. D4.04.0

Correct answer

A. 5.2

Step-by-step solution

Given numbers - 10,9,21,16,24 Mean =10+9+21+16+245=805=16NumbersDistance(d)frommean(16)1069721516024810,9,21,16,24\text{ Mean }=\frac{10+9+21+16+24}{5}=\frac{80}{5}=16 NumbersDistance (d) from mean (16)10697215160248\Sigma d=26Meandeviation=Σd5=265=5.2Mean deviation =\frac{\Sigma d}{5}=\frac{26}{5}=5.2
